DESCRIPTION:
The QS3VH245 has very low ON resistance, resulting in under 250ps
propagation delay through the switch. The switches can be turned ON under
the control of the LVTTL-compatible Output Enable signal for bidirectional data
flow with no added delay or ground bounce. In the ON state, the switches can
pass signals up to 5V. In the OFF state, the switches offer very high impedence
at the terminals.
over-voltage tolerance makes the QS3VH245 ideal forhigh performance
communications applications.
®
The QS3VH245 HotSwitch 8-bit bus switch is a high bandwidth bus switch.
The combination of near-zero propagation delay, high OFF impedance, and
The QS3VH245 is characterized for operation from -40°C to +85°C.
